Redux 工具包从额外的 reducer 获取完整状态

Question

如何从 extraReduces 部分获取完整状态？

createSlice({
    name: 'foos',
    initialState: {
        foos: [],
    },
    reducers: {},
    extraReducers: builder => {
        builder.addCase(
            barAction,
            (state, action) => {
                const barId = action.payload.id; // barAction handler, the payload is the bar's id
                const bar = ??? // getStore().bars[barId]

                state.foo[bar.fooId].baz = true;
            }
        );
    },
});

我想从 Bar 操作中操纵 Foo 切片。但是 Bar 动作负载只是 Bar 实体的 ID。

如果我只有 Bar ID，如何从 Foo 切片中检索 Bar 实体？有什么办法可以得到完整的商店吗？

Answer 1

Redux slice reducers only have access to their own slice of the state，根据定义。

但是，我们确实鼓励 multiple reducers responding to the same dispatched action。
